CVD diamond plate

Chemical vapour deposited (CVD) synthetic diamond is typically produced in a cacuum system below atmospheric pressure, with the carbon atoms supplied from a gas such as methane. The ability to control gas purity makes CVD diamond growth a particularly effective way to make synthetic diamond for applications requiring very high chemical purity, including optical electronic and certain mechanical application

The thermal conductivity of diamond is 1000~2000 w/m.k, which is the highest among all the materials. It is 3 to 5 times than that of copper. Meanwhile, diamond has a small thermal expansion coefficient. So it can largely improve the radiating efficiency by depositing diamond films on common heat sink materials such as Cu and Mo. High-power laser diodes and MCMs (multi-chip three-dimensional assembly technology) are the two main thermal application fields of CVD diamond films.

In this field, the performance of existing heat sink materials can not compete to that of diamond films. The thermal conductivity of the moderate heat sink diamond films can achieve 2-3 times than that of Cu in the room temperature, which is much higher than those of the materials used at present such as AlN, Cu-W alloy, Al2O3 and BeO. It is only inferior to the nature Ⅱa and the Ⅰb synthesized under high pressure high-quality single crystal diamond
